Redundant dependencies

[Igor Bljahhin]

Hello,

My 1.2.4 Play application is packed as standalone WAR using "play war" command. Play puts many dependencies into "WEB-INF/lib" folder and the size of WAR is around 40Mb. Obviously not all JARs are needed and used in the application or by Play. I excluded the following JARs and folders from standalone WAR:

WEB-INF/application/app/controllers/

WEB-INF/application/app/jobs/

WEB-INF/application/app/models/

WEB-INF/application/test/

WEB-INF/application/precompiled/templates/from_play

WEB-INF/classes/application.conf

WEB-INF/classes/messages

WEB-INF/classes/routes

WEB-INF/lib/activation-*.jar

WEB-INF/lib/mail-*.jar

WEB-INF/lib/junit-*.jar

WEB-INF/lib/postgresql-*.jar

WEB-INF/lib/ivy-*.jar

WEB-INF/lib/h2-*.jar

WEB-INF/lib/netty-3.2.5.Final.jar

So far the application is working fine. :) What else, which is not needed in runtime, can be excluded from WAR?

P.S. Below is the list of libraries, which Play puts into WAR file, then "play war" is executed on freshly generated application. There are two versions of "xstream", one of them can be removed, I believe.
